TREM History


The Company, headquartered in Midland, Texas, was originally incorporated in Pennsylvania in 1950 as TREM Corporation.

It was reincorporated in Delaware in 1964, at which time it adopted the name TREM Oil Corporation.

But, the Company’s roots go back to a lumber and banking business in South Pennsylvania and, more directly, to 1907, when the first oil production was established in North Pennsylvania.
